Ingredients
Before you start to make this lazy cake recipe, measure and prepare your ingredients so the cooking process will go smoothly and easily.
Butter- use unsalted butter for this recipe. Only butter will work for this recipe, no margarine, and no coconut oil. Margarine has a weird taste and can ruin the flavor of these delicious cookies.
Dutch cocoa powder– we like to use Dutch-process cocoa powder for our chocolate cake because we like the deep and rich chocolate taste, but the natural cocoa powder will work great as well!
Granulated sugar– we like to use granulated sugar, also the most common sugar used in baking. Caster sugar will work great as well.
Water- use room temperature water.
Vanilla extract- Vanilla extract Is an essential ingredient for chocolate cake.
Vanilla wafers- you will need vanilla wafers for this recipe. If you don’t have vanilla wafers (or vanilla biscuits), you can use vanilla tea biscuits and digestive biscuits.
For the chocolate ganache
Chocolate- use the best quality semisweet or dark chocolate bars for the best flavor. using the best quality dark chocolate is very important in this recipe.
Heavy cream- use full-fat heavy cream for this recipe. the heavy cream makes this chocolate cake. This cant is substituted.
Assembly
Nuts- we used walnuts in this recipe but you can make this recipe with any toasted nuts that you like most like hazelnuts, almonds, pistachios, etc. we highly recommend toasting the nuts before putting them on the cake.
Instructions
Start out with making the chocolate syrup: In a small pan mix together granulated sugar, cocoa powder, and water on low to medium heat.
Add the butter and mix with a whisk until it’s fully melted. Add the vanilla extract and mix for another minute. When the mixture is completely smooth, set the mixture aside to cool for 15 minutes.
Break the biscuit into small pieces with your hands or with a food processor.
Pour the chocolate sauce into the bowl with the biscuits.
Mix well with a wooden spoon until all the biscuit pieces are well coated.
Add the mixture into a parchment paper-lined cake pan and press down the mixture with a spoon. Place in the fridge for 30 minutes.
Make the chocolate ganache
Melt dark chocolate and heavy cream in a small to medium mixing bowl in the microwave for about 50 seconds.
Let the chocolate and the cream sit for 10 minutes for the chocolate to melt, then mix until the chocolate ganache is smooth and silky.
Pour the chocolate ganache on top of the biscuit cake and smooth the top with a spoon.
Cover with plastic wrap and place the biscuit cake in the fridge for at least 4 hours.
Toast walnuts or your favorite nuts in a pan and chop with a sharp knife.
Top the cake with the toasted walnuts. Serve next to a coffee or tea, and enjoy!

My late mother made something called cocoa pie, with social tea biscuits, cocoa, butter and wine. She kept it in the freezer and we loved it. I have been looking for a similar recipe for years! I’m going to add some type of liquor to this recipe and hope it brings back tasty memories. Thank you!
